The principal object ofk myinvention is to improve the construction andioperation of called a star wheel, which advances the elements, such as matrices and space bands, to the assembling point. I

' A feature of `my inventionis the forming of said member with a shelf to receive one of the elements ref-erred to and with a projection or tooth curvedat its outer end, to draw the matrix or space band from said shelf into yassembling position with a wiping or rolling motion instead insteadfof a striking mo- Star wheel.

' Another feature is the arrangement ofsaid shelf at a relatively low point, preferably somewhat below the axis of the star wheel,

vone object of this being to lower said lelements, andv especially the space bands, into position without jar. f

Another feature is that I make my advancing member or star wheel of rubber, preferably medium hard, with (a plastometer Other features will be pointed out below. Inthe drawing f Figure l is an elevation of aportion of a typesetting machine Iembodying my invention;. and

Figure 2 is a detail in elevation on a slightly larger Scale showingthe mounting of the Upon the carriageY 1 is *mountedr the slide linger 2 andthe adjusting screw 3, the member 4 being provided to guide the matrices from the belt 5 to the star wheel or element 6 which advances the matrices to the assembling point, all of this,.except' my member 6,

being well known in the art.

Y The member 6 is mounted which is fixed a friction disk 8. Pinion9 is operated by suitable 'gearing and fits over the disk 8 but is not vsupported by the shaft 7. A portion l0 is mounted on the end of the shaft yand is one abutment for the spring 11, Whose other abutment is pinion 9 so that, in the case of an overset matrix line thev star wheel will stop, the spring permitf ting the pinionv9 to continue revolving by slipping against the disk `8, which with the on shaft 7 to (not shown) wheelis then temporarily held stationary, i

all -of which, except wheel 6, being well known in thisart and being substantially disclosed in U. S.,Letters Patent ,to Groodbody No. 1,657,962' dated January 3,1, 1928.

The space bands may be fed ,through ya chute, not necessary to'be shown'in the draw l ing, which i tobe located directly Vabove the star wheel, whose shelvesv receive thespace bands.

Star wheel 6 rotates in the direction of the arrow in Figure-1 and hasfour projections each havingan outer yendfcurved at 12 and p having' a shelf` 1 3 `uponwhichV the lower end of each matrix 11i y Stantially parallel with the'end ofthe matrix when the latter engages the' shelf. The four projectionsare off. centre,

horizontal left-handk position, beinglower lthanthe horizontal` plane through the axis ofthe star wheel.

A feature of my invention is that mystar wheel is 'made of rubber, preferably medium Y l hard'. rubber with a plastometer of about 201/8 P. Among the advantages of this material I maypoint out that with rubber there is no likelihood of the ymatrix or space band bounding out from the star wheel as the` shelves are not too hardgf ing to the assembling point will not be too vhard and the rubber will have a muchlonger life than the life of the star wheel heretofore used y'and thevmatrices a'ndspace bands will last longer. v

In using my wheel the shelf of one proj ec rests, the yshelf ybeing subl lMoreover the feedany shelf, when in' y i' Ro y tion and the curved outer portion of the next'y following projection cooperate as the wheei rotates to impart a rolling or wiping motion which advances the matrices to assembly position without striking them, `the curved por` the matrix from the shelf. The

position of the shelves is such that they 'receive the space bands at a much lower point than heretofore and thus lowerl the space band to position without jar and by a wiping motion.

What I claim is: f

tion wiping l. A device of the characterdescribed com* l prising a rotary member to advance elements to a desired point and having a shelf, the

plane of which, When the shelf is in horizontal operative position, is substantially lower than the horizontal plane through the axis oi said rotary member, the latter being provided with a portion to remove said elements from v said shelf; `and means to rotate said member.

3. As an article of manufacture for typesetting machines a member tobe `rotateo'l to advance 'matrices or space bands, said member having a shelf the plane of which, when the shelf is in horizontal'operative position, is substantially lower than the horizontal plane through the aXis of said member, the latter being provided with 'a' portion located to ref move the matrices orspace bands Vfrom said 4L. As an article'of manufacture for typesetting machines av member to be rotated to advanee matrices or spacebands, said member being made of rubber and having a shelf,

the plane of which, When the shelf is in hori zontal operative position, is substantially lower than the horizontal plane through the axis of said member, the latter having aprovjection curved at its outer end and located to remove the matrices or space bands from said shelf.
